BEARING-SUPPORT FOR WELL-DRILLING MACHINES.

Specification of Letters Patent.

Patented Aug. 8, 1916.

Application filed October 3, 1914. Serial No. 864,880.

To all whom t may concern Be it known that I, FRANK C. RowLAND, a citizen of the United States, residingat Chanute, in the county of Neosho and State of Kansas, have invented certain new and useful Improvements in Bearing-Supports for lVell-Drilling Machines, of which the following` is a specification, reference being had to the accompanying drawings.

This invention relates to well drilling machines.

rlhe primary object of the invention is to provide an improved bearing or support for the bullwheel shaft ofa well drilling` machine, whereby the bull wheel and the connected drum, together with the bearings, may be readily removed from the frame of the machine so as to facilitate the transportation ofl the machine from place to place.

It is another object of the invention to de; vise an improved bearing for the above purpose, consisting of a suitable supporting post or standard, bracket elements provided with attaching bolts whereby the bearings may be rigidly secured upon the upper ends of the posts, and bracing rods adapted to be detachably connected to said bracket members at one of their ends and securely bolted to base beams at their other ends whereby the standards and the bearings will be rigidly braced and supported.

It is a further general object to improve and simplify the mounting or support for the bull wheel and rope drum of a well drilling machine with a view to increased efliciency in use and material economy in the cost of production of such machines.

Vith theabove and other objects in view, as will appear as the nature of the invention is better understood, the same consists in the novel construction and arrangement of parts of a well drilling machine as will be hereinafter fully described and claimed.

In the accompanying drawings forming a part of this specification, and in which like characters of reference designate corresponding parts: Figure l is a view in side elevation, of a well drilling machine constructed in accordance with the present invention; Fig. 2 is a vertical transverse sectional view, on an enlarged scale, taken on the line 2-2 of Fig. l; Figs. 3 and 4 are detail views of a novel form of bolt used for holding the bull shaft bearing standards assembled with their base.

In the accompanying drawings, I have illustrated a well-known type of well drilling machine which consists generally of a wheel-supported frame having longitudinal sill beams l which are connected at intervals by any desirednumber of transverse frame beams. Upon the beams l, the transverse beams or sleepers 2l are mounted, said sleepers being bolted or otherwise detachably secured to the frame beams. Upon the sleepers at the opposite ends thereof, longitudinal base beams 27 are securely bolted. These beams support the bearing posts or standards 2S upon the upper ends of which the bearings for a shaft 29 are mounted. This shaftcarries a brake wheel 30 which is connected to a bull wheel 31 by means of a drum 32 fixed upon said shaft. Upon this drum, the ordinary tool rope (not shown) is adapted to be wound. The ends of the shaft 29 are mounted in suitable seats provided in the bearing blocks on the upper ends of the posts 28 and are retained in place by the caps 33 which are securely held in position by the attaching plates shown in Figs. 3 and 4 of the drawings. Each of these attaching plates indicated at 34 is provided upon one end with spaced, longitudinally extending, integrally formed bolts 36 having their terminal portions threaded. Upon the end of the plate between these spaced bolts, a reversely bent hook 35 is formed. The spaced bolts 36 are adapted to be disposed through spaced openings in the bearing caps 33, and suitable nuts indicated at 37 are threaded upon the bolts to retain the caps in connection therewith. Each of the plates 34 has spaced openings 3S formed therein to receive bolts 89 transversely disposed through the posts 28, whereby said plates may be rigidly secured to the opposite faces of the bearing post.

40 designates vertically inclined brace or truss rods which are provided upon their upper ends with eyes for engagement with the hooks 35. The lower ends of these rods extend through openings in the base beams 27, and nuts 41 are threaded upon the rods to draw the same downwardly. By this mounting and arrangement of the several parts, it will be apparent that the bearing posts or standards are rigidly braced and supported upon the beams 27, and the bearing caps 33 also securely held against shifting movement. When it is desired, however, to remove the brake wheel together with the bull wheel and the shaft 29, the nuts 4l are removed, whereupon these parts may be lifted, and together with the supporting posts 28 entirely removed from the frame of the machine. By thus detachably mounting the bull wheel shaft and its bearing supports, the weight of the machine is materially lightened, whereby its transportation from place to place may be facilitated. The several parts can also be stored away so that they will not be exposed to the deleterious effects of the elements. It will be apparent that the removal or assemblage of the several parts of the bearing supports may be quickly accomplished so as to place the aparatus in proper condition for actual use.

While-I have above described and illustrate-d in the accompanying drawing the preferred form and construction of the several elements, it is to be understood that the same are susceptible of considerable modification therein and I, therefore, reserve the privilege of adopting all such legitimate changes as may be fairly embodied within the spirit and scope of the invention as claimed.

I claim l. In a well drilling machine, the combination with a bearing standard and a shaft bearing mounted thereon, of plates fixed to the opposite sides of the standard, each of said plates being provided upon its upper end with spaced vertically disposed bolts adapted for engagement through openings in the shaft bearing whereby the bearing may be secured upon the standard, a hook formed upon each of the plates, and vertically inclined brace rods having eyes on their upper downwardly and outwardly curved hook formed on each of the plates between the spaced rods thereof, and vertically inclined brace rods having eyes on their upper ends for engagement with said hooks.

In testimony whereof I hereunto affix my signature in the presence of two witnesses.
